tpecification of Letters Patent.

Application filed July 29, 1915. terial No. T2627.

To all whom it may concern:

Be it known that T, Fnnnnnrcn C. UvnnnURr, a citizen of the United Stateaand a resident of Hillsdale, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Roof-Coverings, of which the following is a specification.

. This invention has relation to roof coverings, consisting of elements adapted to be arranged in overlapping rows in simulation of shingles or tlles.

The invention consists of an improved roofing element. Each element consists of a fibrous body impregnated-with a waterproofing compound such as is ordinarily employed for the purpose, and an external layer of weatherproof material, such as a high -melting-point pitch or asphalt, or crushed mineral material embeddedin such layer of pitch, asphalt or like material on the surface of the body. material is laid upon the surface of the element in fields or areas of contrasting colors, with the material of the darker color so placed upon the exposed portions of the elements as to produce the effect of shadows, and thus to give to the elements an appearance of thickness or of curvature, or of both.

On the accompanying drawing,--

Figure 1 represents a portion of a sheet in the process of manufacture.

Fig. 2 illustrates a finished shingle strip.

Fig. 3 shows a portion of a complete roof.

Figs. 4c and 5 illustrate a sheet, and a shingle strip cut therefrom and having a %ifferent configuration from that shown in Figs. 6 and 7 show another sheet and shingle strip.

Figs. '8 and 9 represent still another form of sheet and a shingle strip cut therefrom, the latter presenting the appearance of a curved tile, when laid.

Fig. 10 shows a portion of a roof covering formed of the strips shown in Fig. 9.

Figs. 11 and 12 represent another form of the roof covering, in which the shadow-lines run only lengthwise of the sheet, to produce the effect of curved surfaces.

Tn accordance with the present invention, after the fibrous or felt sheet 9 has been impregnated or saturated with a suitable water- The crushed mineral proofing compound, and has had the skin coating of pitch or asphalt applied thereto in the usual way, and while the said coating is relatively soft and plastic, crushed mineral material, such as crushed slate, earthen ware, tile or the like, but of different colors or tints, is applied thereto by a suitable machine in such way that certain fields or hands or stripes of different designs of a dark color lie between fields of a brighter or lighter color. Tn F lg. 1, for example, there are formed transverse zigzag bands 10 of a darlr crushed mineral intervening between fields 11 of light colored mineral. Then, by a suit able machine, the sheet is cut transversely along zigzag lines as indicated at 12, so that the cut lies between the side edges of the band 10. As a result of this procedure, there is produced a shingle strip as indicated in Fig. 2, the main body of which has the field 11 of relatively lighter colored crushed mineral, and on its edges the bands or stripes 13, 1 1, are of relatively dark colored mate} rial. Strips such as this are laid in overlapping rows, as shown in Fig. 3, with the result that the stripes 13 or 14c, as the case The bands of darker crushed 17, the shingle strip will be provided along its edges as shown with the two narrow bands 18 and 19 of relatively darlr colored crushed mineral material, Tn Figs. 6 and '2', T have illustrated a method of forming still another shingle strip which is provided with rectangular tabsor projections 20. Tn this case the sheet 18 provided with a series I of zigzag bands 21 of dark crushed mineral material intervening between fields of lighter material. The sheet may be cut into shingle strips, by the use of a machine, as illustrated in my Letters Patent No. 1,182,T1fi or 1,182,417 granted May 9, 1916, the out being so made as to follow the edge of the transverse band 21. Tn this way, along two of the) edges of the tabs, which are exposed lltltl when the strip is laid, there will be a narrow band or stripe 22 of dark colored crushed mineral material.

It will be quite apparent that the roofing elements may be formed with many different outlines or configurations, so that, when laid, they will present the appearance of tiles or shingles of different shapes. In each case, however, the exposed'portion of the element has along its edges the narrow bands or stripes of darker colored material to give the effect of shadows or to accentuate the edges and give the appearance of thickness and solidity If desired, instead of so arranging the coloring matter on the surface of the sheet, as to cause the fiat shingle strips to produce the appearance of only thick flat tiles or shingles, I have found that it is possibleto produce the effect of curved tiles. This may be accomplished by so arranging the coloring matter as to represent the shadows produced by such tiles, so that, when the shingle strips are laid,the roof looks as though it were provided with curved tiles.

In Fig. 8, I have shown a sheet, in which the darker coloring matter is laid in the form of designs each formed by the parallel bands 23, and the curved bands 22. There may also be the narrow parallel lines or'stripes '24. The sheet is cut transversely along the dotted line a2m' to form shingle strips, of which one is shown in Fig. 9. One edge of said sheet has the tabs or projections 25, the extremities of which are straight,

and the side edges of which are of concave curvature. Along the curved portions of the edges are the concentric bands 22 of coloring matter, and on the body of the strip are the bands or stripes 23, 24, all such bands being darker in color than the intervening fields of lighter color. When these shingle strips are laid in overlapping rows,

as shown in Fig. 10, the bands and stripes.

produce the effect of shadows cast by curved tiles of considerable thickness, and the roof I appears to be covered with such tiles.

' In Fig. 11, the stripes of grit 26 and 27 are of different widths, and extend in parallelism longitudinally of the sheet, being of a color different 'in tint or shade from that covering the intervening spaces. The stripes and the intervening bands of grit may be formed on the sheetin accordance with the process described and claimed in my Letters Patent No. 1,154,334, dated September 21, 1915; after which, by a suitable cutting apparatus, the sheet is severed transversely by zigzag or sinuous cutters to produce the complemental edges 28,29. The

edge 28 consists of the straight portions 0 connected by the concaved curved portions b, while the edge 29 comprises the straight portions 0 and the connecting convexly curved portions d. These strips may be laid in overcolor of the asphalt coating.

While I haveillustrated the invention as embodied in a shingle strip having a limited number of tabs or projections, yet it will be apparent that the element might consist of a single prepared shingle or it might equally well consist of a strip of indetermin'ate length. Hence, in using the term roofing element, I mean to include not only shingle strips but single shingles or elongated strips having tabs or projections which, when the strips arelaid in overlapping rows, present the appearance of tiles or shingles.

Having thus explained the nature of my said invention, and described a way of making and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes 'of its use, what I claim is:

1. As a new article of manufacture, a shingle strip formed of waterproofcd fibrous material and having spaced tabs or projections, and adapted to be laid with others in overlapping rows in simulation of shingles, said strip being coated in different fields with grit of contrasting colors, the darker colored grit being laid in stripes or hands adjacent the edges of said tabs to give the appearance of thickness thereto and the lighter colored grit covering the remaining fields.

2. A flat roofing element formed of waterproofed fibrous material and having a portion which isexposed when said element is provided with straight parallel stripes or bands of waterproof coloring matter to produce the illusion of a curved surface.

3. A flat shingle strip formed of waterproofed fibrous material and having on one longitudinal edge spaced tabs or projections of predetermined configuration, said strip.

having on its face crushed waterproof mineral material, the sa d material arranged in different fields 'or areas being laid in bands adjacent the edges of said tabs and in bands longitudinal of said tabs of a darker color'.

than that on the remainder of the face of the strip.

rial, the margins of that serrated portion of mama? the element which is exposed when laid being outlined by stripes or bands of crushed mineral material of a contrasting color.

5. it roofing element consisting of a shingle strip having along one edge tabs or pro j ections which when said strips are laid present the appearance of tiles 0r shingles, said strips being coated with stripes or bands of crushed mineral material adjacent to and outlining with waterproof material the edges of the tabs or projections to accentuate said edges and give them the appearance of greater thickness, the remainder of the surface of the tabs being coated with grit of a. llghter color.

6. The herein described process of makrials. then severing said strip into sections each having tabs or projections of predetermined configuration along one or more of the edges thereoflin such manner that the tabs or projections bear a predetermined relation to said bands or stripes.

7. The herein described process of making illusoryeifect roofing elements, which consists in applying to the adhesive coating of a fibrous sheet, longitudinal bands or stripesof colored grit, then'severing said sheet transversely into sections having tabs or projections of predetermined configuration, so that said tabs or projections bear a predetermined relation to said longitudinal bands or stripes.

In testimony whereof I have afiixed my signature.

FREDERICK C. OVERBURY.
